Smith and Wesson M&P15-22. Picked it up today from Northwest Armory. Also nabbed a 500 round brick of Remington Golden's. Not my favorite ammo, but choices are limited these days. Brought it home and slapped a red/green dot on it that I had laying around. I've owned more than one Bushmaster .223 but ammo prices these days convinced me that a .22 in a true AR form-factor was a must.
